Penstemon pest

I researched possible causes of my penstemon that has some flowers blackened and withered, also has small bugs on it, size of woodlice but look more like baby slugs, they are about the size of a medicinal capsule.

Nematodes but they are not visible? This is a mature yellow penstemon that came with the house ten years ago. I have other much more recent penstemons but none has this problem and I am worried it may spread. It looks unsightly.

Any advice greatly appreciated.
